If you have any issues with your weight and have struggled, please read this book. It is absolutely fascinating and may change your outlook on food and how your body works. Chris read this then passed it on to me, within the first chapter I asked him to help me clear our kitchen and start a new lifestyle. After 4 1/2 weeks we both feel stronger, have more energy, weigh less, and have started a new relationship with food. The 1st half of the book is somewhat of a struggle, however the 2nd half covers the science of how the body processes food, and has helped me change my outlook on how the body works. Read it and see what happens.
